BUCKET CONVEYER.

' SPECIFICATION forming part'of Letters Patent No. 637,716, datedNovember 21, 1899. 7

Application filed December 31, 1897- Serial No. 664,962. (No model.)

To all whmn it ntoty concern:

Be it known that I, JAMES M. DODGE, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Bucket Conveyers, of which the following is aspecification.

My invention relates to that class of pivoted bucket conveyersin whichthe buckets are arranged to overlap, so as to prevent the [0 waste ofmaterial in charging the buckets.

One object of my invention. is to so construct the mechanism that thebuckets will draw away from each other as they pass from a horizontalrun to a vertical run or pass around a wheel and relap as they assumethe position on a horizontal run.

My invention relates, further, to the construction of the feed-chute andalso to the discharging apparatus.

In the accompanying drawings, Figure 1 is a sectional elevation of myimproved pivoted bucket conveyer. Fig. 2 is a transverse section on theline 2 2, Fig. 1. Fig. 3 is a side View of the discharging mechanism.Fig. 4

2 5 is a side view of the feed-chute, and Fig. 5 is a plan view ofthe'.feed-chute.

A are the links of an endless chain pivoted at a, and each link has anarm a, projecting, preferably, at right angles to the link,-and fromthis projection is suspended the pivoted bucketB at b. This pivotedbucket has a lip 19 at one end, and the buckets are so proportioned inrespect to the links that when on either the upper or lower horizontalrun the 3 5 lip of one bucket will overlap the opposite end of anadjoining bucket, as illustrated in the drawings, so that when materialis fed from the chute D the overlapping lips of the buckets will preventthe material from escaping between the buckets.

The conveyer moves in the direction of the arrow 1 and the buckets aredischarged in the direction of the arrow 2, so that the lip on the upperrun is at the rear of the bucket, and thus the bucket can be dumpedwithoutinterfering with the one following.

It will be noticed that as the chain passes around the curve in goingfrom a horizontal to a vertical run the bucket pivoted to the link isdrawn away from the adjoining bucket owing to the fact that it is hungto the link at one side of the center line of the link, in the presentinstance being pivoted to the arm a. By this means the buckets will freethemselves automatically without complicated mechanism and will againoverlap as soon as they return to the horizontal run from a verticalrun.

I have shown in the drawings the feed-chute D pivoted at d to the hopperD, and on the feed-chute are curved plates at, which rest upon thewheels 0 of the conveyer-chain. These wheels are adapted to the rails CO on the horizontal runs, as shown in Fig. 2. By

means of the curved plates on the chute D a rising-and-falling motion isgiven to the chute, so that the material will be intermittently fed tothe several buckets as they pass under the chute.

. In the present instance the buckets are discharged by means of thedevice shown in detail in Fig. 3, which consists of a carriage E, havingwheels e adapted to the rail F. This carriage is guided by rails F,preventing its lifting oif the main rail by the action of the buckets.The carriage has inclined ways e e e c, and on the buckets areprojections i i, which come in contact with the inclined ways. The pin2" first strikes the inclined way e tilting the bucket a portion of thedistance, and then the pin a strikes the inclined way e, discharging theentire contents of the bucket. This pin 11 rides upon the surface of theway 6 until it reaches the inclined way e when the bucket commences toassume its normal position. The projection i will then strike the way 6and the bucket will be guided by it until released therefrom, when itassumes its normal position.

The carriage can be moved along the upper run of the conveyer by meansof a rope g, so as to discharge material at any point through the run.

I claim as my invent-ion 1. The combination in a conveyer, of an endlesschain made up of a series of links, arms projecting from the links,buckets pivoted to said arms, each bucket having a lip adapted tooverlap the edge 01": an adjoining bucket, substantially as described.
